Effect of Exercise Training on the Function of the High Density Lipoprotein (HDL)-Cholesterol, Endothelial Function and Endothelial Progenitor Cells in Patients With Metabolic Syndrome(HERMET-Study)

Randomized, Clinical Trial to Study the Effect of Exercise Training on the Function of HDL-Cholesterol, Endothelial Function, Oxidative Stress and Regenerative Capacity of Endothelial Progenitor Cells in Patients With Metabolic Syndrome

The purpose of the present study is to characterize the quality of HDL-Cholesterol in patients with metabolic syndrome and reduced blood HDL-Cholesterol levels and to examine the effect of exercise training on the vasculoprotective effects of HDL-Cholesterol in these patients. Additionally the investigators aim to investigate the endothelial function, oxidative stress and the regenerative capacity of the endothelial progenitor cells in patients with metabolic syndrome and the changes dependent on physical activity of patients.

Inclusion Criteria:

• Reduced HDL-Cholesterol levels in blood: < 40 mg/dl (1.03 mmol/L) in male, < 50 mg/dl (1.29 mmol/L) in female

• Elevated triglycerides: ≥ 150 mg/dL (1.7 mmol/L
• Elevated blood pressure: ≥ 130 mmHg systolic blood pressure or ≥ 80 mmHg
• diastolic blood pressure or anti-hypertensive treatment
• Elevated fasting glucose: ≥ 100 mg/dL or on drug treatment for elevated fasting glucose

Exclusion Criteria:

• Acute coronary syndrome
• Unstable Angina pectoris
• Myocardial infarction during the last 8 weeks
• Therapy with Niacin
• Active infections
• Ventricular arrhythmias
• Systolic blood pressure > 160 mmHg or diastolic blood pressure > 95 mmHg
